It is a super wide-angle fisheye. On a full frame sensor, it will get the side edges. So just know it is a super wide angle lens that can see 180 degrees and even the edges of the lens. That said, if you are going for something next to 2001 A Space Odyssey or The Cable Guy, aside from another music video. This is the lens for you!
This lens covers Full Frame, Super 35mm and m4/3 digital sensors. This lens is in EF, matches well enough to the Zuiko lenses, which offer a little more yellow vs. amber tones found in the Zenitar lenses.
